The 4 C's of Diamonds

Carat

The term carat actually refers to the diamond's total weight and not its size.

Color

The second most important of the 4Cs is color, which refers to a diamond's lack of color. The less color, the higher the grade.

Clarity

Often the least important of the 4Cs because the tiny imperfections are often microscopic.

Cut

The most important of the 4Cs is cut because it has the greatest influence on a diamond's sparkle.

Fluorescence in Diamonds?

Fluorescence refers to a diamond's tendency to emit a soft colored glow when subjected to ultraviolet light (such as a "black light"). Roughly 30% of diamonds fluoresce to some degree. Colorless (D-F) fluorescent diamonds sell at up to a 15% discount since the fluorescence is perceived as a defect. In fact, the visible effects of Faint to Medium fluorescence are perceptible only to a gemologist using a special UV light source.

Because the fluorescent glow is usually blue (which is the complementary color to yellow) fluorescence can make diamonds of I-M color appear up to one grade whiter. For this reason, I-M diamonds tend to sell at a slight premium when they possess Medium to Very Strong fluorescence.
